The world is so abstract

Humans try/want to find regularity, i.e. laws. Here, regularity ranges from the laws of physics to how to button a suit jacket. Through that endeavor humans achieved so many great things. (e.g. technology) But since abstractness is the essence of the world, humans are fated to fail to find the regularities which have no exception. "I know that I know nothing" is the cleverest statement in history. Being aware of the abstractness, that this world is full of uncertainty and that 'there is no rule' (except math) leads to instability of mind. The wiser you are, the more inescapable it becomes.
